    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Organic fraction of municipal solid waste OFMSW ; Anaerobic digestion; Bioenergy with carbon capture and storage BECCS ; Methane production; 热解，市政污泥，消化物，碳负排放，生物降解垃圾，甲烷，生物能源与碳捕获和储存; pyrolys; slam; rötrester; negative kolemissioner; biologiskt nedbrytbart avfall; metan; BECCS; Teknisk materialvetenskap; Materials Science and Engineering; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

    Abstract : Bioenergy with Carbon Capture and Storage represents a crucial technology that enables an energy production with negative carbon emissions, which is needed to achieve global climate goals. Appropriated management of biodegradable waste, including biodegradable lignocellulosic waste, sewage sludge, organic fraction of municipal solid waste, can make this contribution. READ MORE

  5. 3. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine

    Author : Maja Novakovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RME; HVO; E85; methanol; ethanol; decarbonization; defossilization; heavy-duty; compression-ignition engine; ow temperature combustion; PPC; emissions; PM; particles; aerosol; OA; SOA; DOC;

    Abstract : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. READ MORE

    Abstract : Biochar – the carbon rich residue derived from biomass pyrolysis – is recognised as a potential solution to remove carbon dioxide from the atmosphere, while simultaneously delivering socio-environmental benefits through biochar use as a material. Perceived as a sustainable innovation, biochar has raised interest throughout the world. READ MORE

  7. 5. Stress-induced BVOC emissions from forests in Sweden

    Author : Erica Jaakkola; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volatile organic compounds; Plant stress; Forests; Volatile emissions; spruce bark beetle infestations; ozone stress; wildfire recovery; Picea abies Norway spruce ; Betula pubescens ssp. czerepanovii; Pinus sylvestris Scots pine ; sweden;

    Abstract : A changing climate is expected to lead to more extreme weather events, such as an increased frequency of droughts and forest fires. Changing forest conditions can offer benefits to species such as insects, including bark borers that thrive in warm conditions. READ MORE
